密度和多效唑对江汉平原直播中稻的影响及其品种适应性试验

摘要

In order to solve some technical problems in the production of direct seeding rice in Jianghan plain, effects of different sowing density and paclobutrazol treatment on direct seeding rice were studied, and variety adaptability test was carried out. Though analysis of direct seeding rice growth characteristics and yield characters of different treatments, the rice varieties that suitable for local direct seeding cultivation were selected, providing the relevant technical basis for the direct seeding rice production.%为了解决当前江汉平原直播中稻生产上存在的一些技术问题，对直播中稻开展了不同播种密度和多效唑处理及品种适应性试验。通过分析不同处理下直播中稻生长特性和产量性状，筛选出了适宜当地直播栽培的水稻品种，以期为直播水稻生产提供相关技术依据。
